BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a gaming apparatus such as a roulette gaming machine, bingo gaming machine and the like, and a playing method of the same.

2. Discussion of the Background

Conventionally, when roulette games are played, a dealer throws a ball onto a roulette wheel, in general. However, in recent years, automatization of such roulette games has been advanced, and there have been suggested gaming apparatuses capable of processing roulette games in a full automatic manner, without the dealer throwing in the ball.

Among such gaming apparatuses, there are gaming apparatuses capable of throwing in a ball using air, as disclosed in WO04/094013A1. Gaming apparatuses which process roulette games in a full automatic manner are desired to drop and house a ball into respective pockets with an even probability. Therefore, among these gaming apparatuses, there are some gaming apparatuses designed to include a ball track having concavities and convexities on its surface for disturbing the behavior of the ball, in order to cause the ball to drop into respective pockets with an even probability.

It is an object of the present invention to enable changing the probabilities that a ball is housed in respective pockets as required, thereby offering new entertainment.

The contents of WO 04/094013 A1 are incorporated herein by reference in their entirety.

DESCRIPTION OF THE EMBODIMENTS

A first aspect of the present invention is an invention for extracting control data to be a reference target, based on pattern data. A second aspect of the present invention is an invention made by modifying the first aspect of the present invention in such a way that a plurality of pattern data exist, and the pattern data is changed when a second predetermined condition is satisfied. A third aspect of the present invention is an invention made by modifying the second aspect of the present invention in such a way that the pattern data is changed when a series of control data is changed.

In the following description, the term “the present invention” refers to the first aspect of the present invention, the second aspect of the present invention and the third aspect of the invention.

Hereinafter, an embodiment according to the third aspect of the present invention will be described.

FIGS. 1A and 1B are a plan view of a roulette device according to the present embodiment. FIG. 2 is a view illustrating an exemplary series of control data. FIG. 3 is a view illustrating exemplary pattern data. FIG. 4 is an external perspective view illustrating the general structure of a roulette gaming machine according to the present embodiment. While the roulette gaming machine 1 is a standalone type gaming machine which is not connected to a network, the present invention can be applied to a gaming machine connected to a network.

As illustrated in FIG. 1A, the roulette device 3 included in the roulette gaming machine 1 (see FIG. 4) includes a frame member 21 secured to a cabinet 2 (see FIG. 4), and a roulette wheel 22 which is rotatably housed and supported inside the frame member 21. On an upper surface of the roulette wheel 22, there are formed a large number of concave-shaped number pockets 23 (a total of 38 number pockets in the present embodiment). Further, on the upper surface of the roulette wheel 22 in the outer directions of the respective number pockets 23, there are formed number display plates 25 displaying respective numbers of “0”, “00”, and “1” to “36”, in association with the respective number pockets 23.

A ball throwing port 36 is formed in the frame member 21. A ball throwing device 104 (see FIG. 9) is connected to the ball throwing port 36, so that a ball 27 can be thrown onto the roulette wheel 22 from the ball throwing port 36 by being driven by the ball throwing device 104. Further, the roulette device 3 is entirely covered with a hemispherical transparent acrylic cover member 28 (see FIG. 4) thereabove.

Below the roulette wheel 22, there is provided a wheel-driving motor 106 (see FIG. 9), so that the roulette wheel 22 is rotated by being driven by the wheel driving motor 106.

Further, metal plates (not illustrated) are mounted at predetermined intervals below the roulette wheel 22, and these metal plates are detected by a proximity sensor included in a pocket position detection circuit 107 (see FIG. 9), which enables detecting the positions of the number pockets 23.

The frame member 21 is gently inclined in an inward direction, and a guide wall 29 is formed at a middle position thereof. The guide wall 29 is for guiding the thrown ball 27 against a centrifugal force to cause the ball 27 to roll. As a rotation speed of the ball 27 decreases and, thus, the centrifugal force thereof decreases, the ball 27 rolls along the inclined surface of the frame member 21 and travels inwardly to reach the rotating roulette wheel 22. Then, the ball 27 which has rolled and reached the roulette wheel 22 passes over the number display plates 25 outside the still rotating roulette wheel 22 and then is housed in one of the number pockets 23. As a result, a ball sensor 105 (see FIG. 9) detects the number displayed to the number display plate 25 corresponding to the number pocket 23 housing the ball, and this number becomes a winning number.

Rotation of the roulette wheel 22 and launching of the ball 27 are performed based on control data.

As illustrated in FIG. 2, in the present embodiment, there are a plurality of series of control data (6 series of control data, in the present embodiment), wherein a single series of control data includes 6 control data.

The control data includes motor driving time, ball initial speed and launching delay time.

The motor driving time is for driving the wheel driving motor 106 (see FIG. 9). The roulette wheel 22 is rotated at a predetermined rotation speed by the wheel-driving motor 106 for a length of time corresponding to a motor driving time. Further, after the roulette wheel 22 is released from the driving by the wheel-driving motor 106, the rotation speed of the roulette wheel 22 gradually decreases and the roulette wheel 22 finally stops. Further, the ball initial speed is an initial speed for throwing the ball 27 from the ball throwing device 104. The launching delay time is a time since a predetermined number pocket 23 passes through a predetermined position until a ball is launched, during the rotation of the roulette wheel 22.

As illustrated in FIG. 1A, the roulette wheel 22 is divided into 6 areas, which are areas A to F. Each area is constituted by 6 or 7 number pockets 23 adjacent to one another.

The respective control data are determined so as to provide a higher weight on the probability that the ball 27 is housed in one of the areas A to F. For example, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data (control data 1A) of “a motor driving time of 10 sec, a ball initial speed a and a launching delay time of 0,” the respective control data are determined so as to provide a higher weight on the probability that the ball 27 is housed in the area A.

Similarly, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data 1B, the probability that the ball 27 is housed in the area B becomes higher. Further, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data 1C, the probability that the ball 27 is housed in the area C becomes higher. Further, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data 1D, the probability that the ball 27 is housed in the area D becomes higher. Further, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data 1E, the probability that the ball 27 is housed in the area E becomes higher. Further, when the rotation of the roulette wheel 22 and the launching of the ball 27 are controlled based on the control data 1F, the probability that the ball 27 is housed in the area F becomes higher.

A series of control data is constituted by a plurality of control data, each of the control data corresponds to an area among a plurality of areas (groups) the roulette wheel is divided into.

A series of control data may be data that all the pockets assuredly belong to any of the high-probability areas determined by each control data, as in the present embodiment, and may also be data that there exists a pocket which does not belong to any of the high-probability areas determined by any control data.

In the present embodiment, the roulette wheel 22 rotates counterclockwise, and the ball 27 moves clockwise. For example, when the ball initial speed and the launching delay time are fixed, as the motor driving time is made longer, an area with a high probability of housing the ball 27 (hereinafter also referred to as a high probability area) is changed in the following order: A→B→C→D→E→F→A and so forth.

Further, for example, when the motor driving time and the launching delay time are fixed, as the ball initial speed is made higher, the high probability area is changed in the following order: A→B→C→D→E→F→A and so forth.

Moreover, for example, when the motor driving time and the ball initial speed are fixed, as the launching delay time is made longer, the high probability area is changed in the following order: A→B→C→D→E→F→A and so forth.

Accordingly, in the present invention, when the control data includes any one of data on wheel rotation control (motor driving time), data on timing for launching the ball (launching delay time), and data on the initial speed of the ball being launched (ball initial speed), a plurality of control data different in high probability area can be set, thereby providing different weights on the probability of each number pocket 23 housing the ball 27.

Further, in the present embodiment, when the initial speed is changed from an initial speed “a” to an initial speed “b”, from the initial speed “b” to an initial speed “c”, from the initial speed “c” to an initial speed “d” and so forth, the high probability area is shifted by one area (e.g. the area is shifted from the area A to the area B). Further, every time the launching delay time is made longer by 0.1 second, the high probability area is shifted by one area. Moreover, every time the motor driving time is made longer by 1 second, the high probability area is shifted by five areas. Therefore, by combination of these, it is possible to set a plurality of control data different in high probability areas, so as to provide different weights on the probability of the each number pocket 23 housing the ball 27.

As in the present embodiment, when the control data is data including the combination of the data on wheel rotation control (motor driving time), the data on timing for launching the ball (launching delay time), and the data on the initial speed of the ball being launched (ball initial speed), apparent variations with respect to the player (e.g. the rotating time of the roulette wheel 22 is long, the initial speed of the ball 27 is high) can be involved.

Friction at the rotational axial section of the roulette wheel 22, the surface shape of the roulette wheel 22 (e.g. depression or distortion), and the like may vary among the roulette gaming machines 1 due to a variety of factors in manufacturing thereof. Hence there is a case where, even when common control data is used in each of the roulette gaming machines 1, the areas where the ball 27 is finally housed vary among the roulette gaming machines 1. Therefore, the control data may be set such that, for example, after completion of the manufacturing, tests are conducted with a variety of parameters included in the control data being changed as appropriate, to organize statistics concerning which parameter may allow which area to have a high probability of housing the ball 27. Namely, the control data may vary among the roulette gaming machines 1.

Moreover, even when the areas that finally house the ball 27 vary among the roulette gaming machines 1, the common control data may be used in each of the roulette gaming machines 1. This is because the probability of housing the ball in some area should just be relatively high based on the control data in each of the roulette gaming machines 1.

While, in the example, there has been described a case where the areas A to F are constituted by 6 or 7 number pockets 23 adjacent to one another, there is no particular limitation on the number of pockets belonging to a single group, in the present invention. Further, the respective groups can be constituted by the same number of pockets or different numbers of pockets.

Further, while, in the example, there has been described a case where the number pockets 23 are divided into the 6 areas (groups), which are the areas A to F, the number of areas (groups) is not limited to 6 in the present invention.

In the example, there has been described a case where the areas A to F are not overlapped with one another. Namely, there has been described a case where the pockets belonging to a single group do not belong to the other groups. However, the present invention is not limited thereto, and a single pocket can belong to a plurality of groups.

While, in the example, there has been described a case where a plurality of control data are provided in association with the respective areas (groups), it is necessary only that a plurality of control data are provided, but it is not necessary that they are associated with the respective areas (groups), in the present invention.

While, in the example, there has been described a case where the control data is constituted by motor driving time, ball initial speeds and launching delay time, the control data of the present invention is not limited thereto, but may be data including one of data relating to wheel rotation control (motor driving time), data relating to a timing of ball launching (launching delay time), and data relating to an initial speed for launching a ball (ball initial speeds), or a combination thereof.

Such data relating to wheel rotation control may be, for example, rotation speeds of the roulette wheel when it is driven by the motor, as well as motor driving time.

While, in the example, the case was described where the control data corresponds one-to-one to the area, e.g. control data with “the motor driving time: 10 sec, the ball initial speed: a, the launching delay time: 0” corresponds to the area A. However, the control data in the present invention is not limited thereto so long as the control data serves to perform control so as to provide different weights on the probability of each of the pockets housing the ball. For example, the control data may be data where the probability of the pocket housing the ball is fixed, the pocket belonging to each area (group), e.g., the probability that the number pocket 23 belonging to the area A houses the ball 27 is 70%, the probability that the number pocket 23 belonging to the area B houses the ball 27 is 20%, or the probability that the number pocket 23 belonging to the area C houses the ball 27 is 10%. In such a configuration, for example, a single group may be determined based on the above probabilities to control such that the pocket belonging to the determined group houses the ball.

The areas A′ to F′ illustrated in FIG. 1B are displaced from the areas A to F in FIG. 1A by an amount corresponding to two pockets each, in the direction of the clockwise rotation of the roulette wheel 22. Each of the areas A′ to F′ is the area to be a high-probability area controlled by each control data 2A′ to 2F′ constituting the series of control data 2 in FIG. 2. Although the number of areas is 6 in any case where the roulette wheel is divided into areas as in FIG. 1A or FIG. 1B, the numbers belonging to the respective areas are different between these cases.

In the present embodiment, there will be described a case where the number of areas which are to be high-probability areas controlled by control data constituting a single series of control data, is fixed (6 areas), and the numbers belonging to the respective areas are different according to the respective series of control data.

However, in the present invention, the method for dividing the roulette wheel into areas is not limited to the above-mentioned case. For example, the number of areas which are to be high-probability areas may be different according to the respective series of control data, i.e., the roulette wheel may be divided into 4 areas with respect to the control data constituting a single series of control data, or the roulette wheel may be divided into 7 areas with respect to the control data constituting another series of control data. This can be realized by providing the respective series of control data with the same number of control data as the number of areas to be high-probability areas.

Further, in the present invention, the number of series of control data is not limited to 6 so long as there are provided 2 or more of series of control data, in the third aspect of the present invention. Further, in the first and second aspects of the present invention, there may be provided either one series of control data or a plurality of them.

The control data to be a reference target is switched at every predetermined time (for example, at the 0-th minute of every hour). At the predetermined time, a single control data is selected out of the plurality of control data constituting the currently set series of control data, based on the currently set pattern data out of the plurality of pattern data illustrated in FIG. 3.

In the present embodiment, 6 pattern data illustrated in FIG. 3 are stored in the ROM 102 (see FIGS. 9 and 10). For example, according to the pattern data P1, control data is selected so as to shift the high-probability area to the adjacent area in the direction of the clockwise rotation of the roulette wheel 22, at the timing of changing the control data. Further, for example, according to the pattern data P3, control data is selected so as to shift the high-probability area to every other area in the direction of the clockwise rotation of the roulette wheel 22.

In the present invention, the number of pattern data is not limited to 6 so long as there are provided 2 or more of pattern data, in the third aspect of the present invention. Further, in the first and second aspects of the present invention, there may be provided either one pattern data or a plurality of them.

Further, in the present invention, the content of the pattern data is not limited to the case illustrated in FIG. 3, but there may be provided, for example, pattern data which shifts the high-probability area to the area at the diametrically opposite position about the center of rotation of the roulette wheel. Also, there may be provided, for example, pattern data which shifts the high-probability area to the area at the diametrically opposite position about the center of rotation of the roulette wheel 22, then shift to the adjacent area in the direction of the clockwise rotation and then shift to the area at the diametrically opposite position about the center of the rotation, again.

The pattern data is changed when the series of control data is changed. When the series of control data is changed, a single pattern data is selected at random out of the 6 pattern data illustrated in FIG. 3.

While, in the present embodiment, there will be described a case where pattern data is selected at random, the method for selecting the pattern data is not limited thereto, in the present invention. For example, a single pattern data may be selected in a predetermined order, such as the order of P1, P2, P3, and so forth, out of the plurality of pattern data illustrated in FIG. 3.

Further, the series of control data is changed when the number of games has reached a predetermined number (for example, 5). “The number of games” refers to the number of games which have been played.

Next, the structure of the roulette gaming machine 1 will be described.

Further, specific BET areas are similarly arranged in a grid shape, wherein the specific BET areas are for specifying “odd numbers”, “even numbers”, “the types of colors of the number display plates (red or black)”, “certain numerical ranges (for example, “1” to “12” and the like) so that chips can be betted thereon.

Under the table-type betting board 60, there are displayed a result history display portion 65, unit BET buttons 66, a payback result display portion 67, and a number-of-credit display portion 68.

The result history display portion 65 displays a list of winning numbers resulted from the previous games (in this case, “a single game” refers to a series of operations starting with betting by a player in any of the stations 4 and then throwing the ball 27 into the number pockets 23 and ending with paying back credits based on the winning number). In this case, when a single game ends, a new winning number is added and displayed to the top of the list, which enables recognizing the history of winning numbers resulted from up to 16 games.

Further, the unit BET buttons 66 are for betting chips on a BET area 72 (over a grid having a number or mark or over a line defining grids) specified by the player. The unit BET button 66 is constituted by four buttons, which are a 1-BET button 66A, a 5-BET button 66B, a 10-BET button 66C and a 100-BET button 66D.

At first, the player specifies a BET area 72 on which he or she desires to bet, with a cursor 70 which will be described later, by directly pushing it on the screen. By pushing the 1-BET button 66A at this state, the player can bet one chip at a time (i.e., every time the 1-BET button 66A is pushed with fingers or the like, the number of bets is increased in the order of “1”, “2”, “3” and so forth). By pushing the 5-BET button 66B, the player can bet five chips at a time (i.e., every time the 5-BET button 66B is pushed with fingers or the like, the number of bets is increased in the order of “5”, “10”, “15” and so forth). By pushing the 10-BET button 66C, the player can bet ten chips at a time (i.e., every time the 10-BET button 66C is pushed with fingers or the like, the number of bets is increased in the order of “10”, “20”, “30” and so forth). Further, by pushing the 100-BET button 66D, the player can bet chips 100 chips at a time (i.e., every time the 100-BET button 66D is pushed with fingers or the like, the number of bets is increased in the order of “100”, “200”, “300” and so forth).

The payback result display portion 67 displays the number of chips betted by the player and the number of paid-back credits in the previous game. In this case, the number of paid-back credits minus the number of betted chips indicates the number of credits that the player newly acquired in the previous game.

The number-of-credit display portion 68 displays the number of credits possessed by the current player. If chips are betted, the number of credits is decreased by an amount corresponding to the number of bets (1 bet corresponds to 1 credit). In the event of that winning relating to the betted chips occurs and credits are paid back, the number of credits is increased by the number of paid-back credits. Further, if the number of credits possessed by the player becomes 0, the games end.

Further, above the table-type betting board 60, a BET time display portion 69 is provided. The BET time display portion 69 displays the remaining time during which the player can bet. The BET time display portion 69 displays “20” at the start of reception of betting operations, then decreases the number by one at every second and displays “0” at the end of reception of betting operations. Further, when the remaining betting time for the player reaches 5 seconds at each station 4, the ball throwing device is driven to throw the ball 27 onto the roulette board.

Further, to the right of the BET-time display portion 69, there are provided a MEGA display portion 73 which displays the number of credits accumulated for the JP “MEGA” until the present time, a MAJOR display portion 74 which displays the number of credits accumulated for the JP “MAJOR” until the present time, and a MINI display portion 75 which displays the number of credits accumulated for the JP “MINI” until the present time. The MEGA display portion 73 displays a number of credits resulted from cumulatively accumulating 0.15% of the credits betted in every single game at all 12 stations 4. The MAJOR display portion 74 displays a number of credits resulted from cumulatively accumulating 0.20% of the betted credits. The MINI display portion 75 displays a number of credits resulted from cumulatively accumulating 0.30% of the betted credits. The MEGA display portion 73, the MAJOR display portion 74 and the MINI display portion 75 display numerical values which are common among all the stations 4. In the event that the player wins a JP during a JP bonus game, the credits for the JP won by the player are paid out, out of the three types of JP displayed to the display portions 73 to 75, and, after the paying out, the JP display portion displays an initial numerical value (i.e., 200 credits for “MINI”, 5000 credits for “MAJOR” and 50000 credits for “MEGA”).

Further, on the table-type betting board 60, the cursor 70 indicating the BET area 72 being currently selected by the player is displayed. Further, a chip mark 71 indicating the number of chips betted up to the present time and the BET area 72 is displayed, wherein the number displayed to the chip mark 71 indicates the number of betted chips. For example, as illustrated in FIG. 5, a “7” chip mark 71 placed on the “18” grid indicates that 7 chips are being betted on the number “18”. Further, such a method for betting on only a single number is a betting method called “Straight Bet”.

Further, a “1” chip mark 71 placed at the intersection of the “5”, “6”, “8” and “9” grids indicates that all the four numbers are covered, meaning a single chip is being betted on the four numbers “5”, “6”, “8” and “9”. Further, such a method covering four numbers for betting on the four numbers is a betting method called “Corner Bet”.

As other betting methods, there are “Split Bet” which covers two numbers using the line between the two numbers so as to bet on two numbers; “Street Bet” which covers three numbers using an end of a lateral single row of numbers (a vertical single row, in FIG. 5) so as to bet on three numbers (for example, “13”, “14” and “15”); “Five Bet” which covers five numbers using the line between the numbers “00” and “3” so as to bet on five numbers “0”, “00”, “1”, “2” and “3”; “Line Bet” which covers six numbers using the space between two lateral rows of numbers (two vertical rows in FIG. 5) so as to bet on six numbers (for example, “13”, “14”, “15”, “16”, “17” and “18”); “Column Bet” which covers twelve numbers using a “2-to-1” grid so as to bet on twelve numbers; and “Dozen Bet” which cover twelve numbers using any of “1st-12”, “2nd-12” and “3rd-12” grids so as to bet on twelve numbers. Further, there is a method which covers 18 numbers so as to bet on 18 numbers, by specifying the 18 numbers from any of the colors of the number display plates (“red” or “black”), odd numbers or even numbers, and numbers equal to or less than 18 or numbers equal to or greater than 19, using 6 grids provided at the lowermost stage of the table-type betting board 60. In this case, these plurality of betting methods result in different credit payout values (payout value ratios) per single chip, in the event of the occurrence of winning relating to betted chips.

When a player performs betting through the BET screen 61 having the above-mentioned configuration, the player specifies a BET area 72 (over a grid having a number or mark or over a line defining grids) on which he or she desires to bet, by directly pushing it on the screen with his or her finger. As a result, the cursor 70 moves to the specified BET area 72.

Thereafter, by pushing each unit button (the 1-BET button 66A, the 5-BET button 66B, the 10-BET button 66C and the 100-BET button 66D), out of the unit BET buttons 66, a number of chips corresponding to the number of units are betted on the specified BET area 72. For example, by pushing the 10-BET button 66C four times, pushing the 5-BET button 66B a single time and pushing the 1-BET button 66A three times, it is possible to bet a total of 48 chips.

FIG. 11 is a block diagram illustrating the internal structure of a station according to the present embodiment. Further, the twelve installed stations 4 have basically the same structure and, therefore, a single station 4 will be exemplarily described, hereinafter.

As illustrated in FIG. 11, the station 4 includes a station control portion 90 constituted by a station-controlling CPU 91, a ROM 92 and a RAM 93. The ROM 92 is constituted by, for example, a semiconductor memory or the like and stores programs for realizing basic functions of the station 4, other programs of various types necessary for controlling the station 4, data tables and the like. Further, the RAM 93 is a memory for temporarily storing various types of data resulted from calculations by the station-controlling CPU 91, the number of credits currently possessed by the player (accumulated in the station 4), the condition of betting of chips by the player, and the like.

Further, a BET confirmation button 47, a payback button 48 and a help button 49, which are provided in the control portion 7 (see FIG. 4), are connected to the station-controlling CPU 91.

The BET confirmation button 47 is to be pushed for confirming betting after betting operations through the image display device 8.

The payback button 48 is to be generally pushed at the end of games. When the payback button 48 is pushed, a number of medals corresponding to the credits acquired in games and the like and currently possessed by the player (a single medal for a single credit, in general) are paid out from the medal payout port 9.

The help button 49 is to be pushed when the game operating method or the like is unknown. Immediately after the help button 49 is pushed, a help screen describing information on various types of operations is displayed to the image display device 8.

The station-controlling CPU 91, based on operation signals issued by pushing respective buttons and the like, controls the station 4 for conducting various types of operations corresponding to the operation signals. More specifically, the station-controlling CPU 91 conducts various types of processing, based on input signals that the control portion 7 supplies thereto on receiving inputs of operations by the player, and data and programs stored in the ROM 92 and the RAM 93. Then, the station-controlling CPU 91 transmits the result of such processing to the server-controlling CPU 81.

The program ROM stores image-controlling programs relating to the display on the image display device 8, and various types of selection tables. The image ROM stores, for example, dot data for use in forming images to be displayed to the image display device 8. The image-controlling CPU is for determining images to be displayed to the image display device 8, out of the dot data pre-stored in the image ROM, according to the image-controlling programs pre-stored in the program ROM, based on parameters set in the station-controlling CPU 91. The work RAM is formed as a temporal storage device for use in executing the image-controlling programs with the image-controlling CPU. The VDP creates images corresponding to the content of display determined by the image-controlling CPU and outputs them to the image display device 8. Further, the video RAM is formed as a temporal storage device for use in creating images with the VDP.

Further, the touch panel 50 is provided in the front surface of the image display device 8 as previously described, and information on operations on the touch panel 50 is transmitted to the station-controlling CPU 91. On the touch panel 50, the player performs operations for betting chips through the BET screen 61. More specifically, the touch panel 50 is operated in selecting BET areas 72, operating the unit BET buttons 66 and the like, and information on such operations is transmitted to the station-controlling CPU 91. Then, based on such information, information on the betting by the current player (i.e., information on the BET areas specified on the BET screen 61 and the number of chips betted thereon) is stored in the RAM 93 anytime. Further, the betting information is transmitted to the server-controlling CPU 81 and is stored in the BET information storage area of the RAM 83.

The medal sensor 97 detects medals inserted from the medal insertion port 6 (see FIG. 4), calculates the value of the inserted medals and transmits the result to the station-controlling CPU 91. The station-controlling CPU 91, based on the transmitted signals, increases the number of credits possessed by the player which is stored in the RAM 93.

The WIN lamp 11 is connected to the station-controlling CPU 91. The station-controlling CPU 91 lights the WIN lamp 11 in predetermined colors, in the event of the occurrence of winning relating to chips betted on the BET screen 61 or the winning of JP.

Hereinafter, based on FIGS. 12 and 13, there will be described server-side game processing which is conducted by the server-controlling CPU 81 included in the roulette gaming machine 1 according to the present embodiment, and station-side game processing which is conducted by the station-controlling CPU 91. FIG. 12 and FIG. 13 are flow charts illustrating game processing in the roulette gaming machine according to the present embodiment.

First, the station-side game processing will be described, based on FIG. 12 and FIG. 13.

At first, in step S11, the station-controlling CPU 91 determines whether or not medals or coins have been inserted by the player, based on detection signals from the medal sensor 97. If no medal or coin has been inserted (step S11: NO), the station-controlling CPU 91 waits for medals or coins to be inserted. On the other hand, if medals or coins have been inserted (step S11: YES), the processing proceeds to step S12.

In step S12, the station-controlling CPU 91 stores, in the RAM 93, an amount of credit data corresponding to the number of inserted medals or coins. Next, in step S13, the station-controlling CPU 91 transmits, to the server 13, a medal detection signal indicative of the presence of insertion of medals or coins.

Next, in step S14, the station-controlling CPU 91 causes the image display device 8 in the station 4 to display the BET screen 61 illustrated in FIG. 5.

Next, in step S15, the station-controlling CPU 91 starts measurement of a betting time period during which the player can bet chips.

Then, the player taking part in the game can bet his or her own chips on a BET area 72 relating to a winning number that he or she predicts, by operating the touch panel 50, during the betting time period during which betting can be received (see FIG. 5). Betting methods using the BET screen 61 have been already described in detail, and description thereof is not repeated.

Further, the player is allowed to take part in a game halfway therethrough after the start of the betting time period, and up to 12 players can play games with the roulette gaming machine 1 according to the present embodiment. Further, in cases where a current game is played subsequently to the previous game, the reception of betting operations is started immediately after the end of the previous game.

Next, in step S16, on receiving a betting-time-period end signal indicative of the end of the betting time period from the server-controlling CPU 81, the station-controlling CPU 91 causes the image display device 8 in the station 4 to display an image indicative of the end of the betting time period, and ends the reception of betting operations through the touch panel 50 (step S17). Thereafter, the station-controlling CPU 91 transmits information on the betting that the player performed at the station 4 (i.e., information on the specified BET area 72, the number of chips betted on the specified BET area 72 [i.e., the number of bets]) (step S18).

Next, in step S19, the station-controlling CPU 91 receives, from the server 13, the result of JP-bonus-game determination processing conducted by the server-controlling CPU 81, which will be described later. The result of JP-bonus-game determination includes the result of determination as to whether or not a predetermined JP bonus game should be generated at each station 4, the result of determination as to which station 4 out of the 12 stations 4 should win a JP (or as to whether all the stations 4 should not win the JP) if a JP bonus game should be generated, the result of determination as to which JP (“MEGA”, “MAJOR” or “MINI”) should be generated if a JP should be generated, and the like.

Next, in step S20 in FIG. 13, the station-controlling CPU 91 determines whether or not a JP bonus game should be generated, based on the result of the JP-bonus-game determination processing which was received in step S19. If the station-controlling CPU 91 determines that a JP bonus game should be generated at this station 4, the station-controlling CPU 91 executes a predetermined selectable JP bonus game relating to acquisition of JPs and causes the image display device 8 to display the result of the game (i.e., whether or not a JP was acquired), based on the result of determination received in step S19.

If the station-controlling CPU 91 determines in step S20 that no bonus game should be generated at this station 4, or after the processing in step S21, the station-controlling CPU 91 receives the result of credit payout transmitted from the server-controlling CPU 81 (step S22). The result of credit payout is constituted by the result of payout in games and the result of JP payout in JP bonus games.

Next, in step S23, the station-controlling CPU 91 pays out credits, based on the result of payout received in step S22. More specifically, the station-controlling CPU 91 stores, in the RAM 93, an amount of credit data corresponding to the payout value of the game and, also, stores therein, an amount of credit data corresponding to the JP payout value accumulated until the present time in cases where a JP bonus game was generated and the present station 4 won a JP. Then, if the payback button 48 is pushed, a number of medals corresponding to the number of credits currently stored in the RAM 93 (a single medal corresponds to a single credit, in general) are paid out from the medal payout port 9.

If a game is continuously played at one of the stations 4 thereafter, the processing returns to step S14, then starts the betting time period again and enters the next game.

On the other hand, if the game is ended at all the stations 4, the game processing ends.

Next, based on FIG. 12 and FIG. 13, the server-side game processing will be described.

At first, in step S101, the server-controlling CPU 81 determines whether or not medals or coins have been inserted by the player, on receiving medal detection signals transmitted from the station-controlling CPU 91. In the roulette gaming machine 1 according to the present embodiment, if medals or coins are inserted at one of the stations 4, the station-controlling CPU 91 in the station 4 at which the medals or coins have been inserted transmits a medal detection signal to the server-controlling CPU 81.

Next, the server-controlling CPU 81 starts measurement of a betting time period, at the time point when the player who first takes part in the game inserts medals or coins (step S102). The betting time period is a time period during which players can perform inputs for betting. Players taking part in the game can bet their own chips on BET areas 72 relating to winning numbers they predict, by operating the touch panel 50 during the betting time period.

Next, in step S103, the server-controlling CPU 81 determines whether or not the remaining betting time period has reached 5 seconds. Further, the remaining betting time period is displayed to the BET time display portion 69 (see FIG. 5). If it is determined that the remaining betting time period has not reached 5 seconds, the processing is returned to step S103. On the other hand, if it is determined that the remaining betting time period has reached 5 seconds, the processing shifts to step S104.

In step S104, the server-controlling CPU 81 transmits a control signal for starting an operation of the roulette device 3, to the CPU 101 in the roulette device 3. The CPU 101, on receiving the control signal, refers to the control data stored in the ROM 102 and controls operations as follows.

First, the CPU 101 drives the wheel driving motor 106 to rotate the roulette wheel 22, only during a motor driving time defined by the control data.

Then, after the elapse of a predetermined time period (for example, 20 seconds) since the start of the rotation of the roulette wheel 22, the CPU 101 throws the ball 27 after the elapse of a launching delay time since it detected a detection signal from the pocket position detection circuit 107. At this time, the ball is thrown at an initial speed defined by the control data.

As control data to be referred by the CPU 101, single control data has been pre-set as a reference target, at the time of activation of the roulette gaming machine 1. Further, when another control data is set as the reference target, this another control data is referred to as the reference target by the CPU 101.

Next, in step S105, the server-controlling CPU 81 determines whether or not the betting time period has ended. If the server-controlling CPU 81 determines that the betting time period has not ended, it waits for the end of the betting time period.

On the other hand, if the server-controlling CPU 81 determines that the betting time period has ended, the server-controlling CPU 81 transmits a betting-time-period end signal indicative of the end of the betting time period, to the station-controlling CPU 91 (step S106).

Next, in step S107, the server-controlling CPU 81 receives, from the station-controlling CPU 91, information on the betting that the player performed at each station 4 (i.e., information on the specified BET area 72, the number of chips betted on the specified BET area 72 [i.e., the number of bets] and the betting method) and stores it in the BET information storage area 83A in the RAM 83.

Next, in step S108, the server-controlling CPU 81 cumulatively adds a number of credits corresponding to 0.30% of the sum of the credits betted at all the stations 4, which were received in step S107, to the JP value stored in the “MINI” JP cumulative storage area 83C in the RAM 83. Further, the server-controlling CPU 81 cumulatively adds a number of credits corresponding to 0.20% of the sum of the credits to the JP value stored in the “MAJOR” JP cumulative storage area 83D in the RAM 83. Further, the server-controlling CPU 81 cumulatively adds a number of credits corresponding to 0.15% of the sum of the credits to the JP value stored in the “MEGA” JP cumulative storage area 83E in the RAM 83. Further, based on these JP values, the server-controlling CPU 81 updates the displays on the JP-value display portion 15, the MEGA display portion 73, the MAJOR display portion 74 and the MINI display portion 75.

Next, in step S109, the server-controlling CPU 81 conducts JP-bonus-game determination processing. In this processing, using random numbers sampled by a sampling circuit and the like, the server-controlling CPU 81 determines whether or not a JP bonus game should be generated at each station 4, determines which station 4 out of the 12 stations 4 should win a JP (or whether all the stations 4 should not win a JP) if a JP bonus game should be generated, and also determines which JP (“MEGA”, “MAJOR” or “MINI”) should occur if a JP should be generated.

Next, in step S110, the server-controlling CPU 81 transmits the result of JP bonus game determination to each station 4, based on the processing in step S109.

Next, in step S111 in FIG. 13, the server-controlling CPU 81 transmits a control signal to the roulette device 3 to drive the ball sensor 105, thereby determining which number is associated with the number pocket 23 in which the ball 27 has been housed.

Next, the server-controlling CPU 81 determines whether or not winning relating to the chips betted at each station 4 has occurred, from the betting information on each station 4 which was received in step S107 and the type of the pocket determined in step S111 (step S112).

Next, in step S113, the server-controlling CPU 81 conducts a payout value calculation processing. In the payout value calculation processing, the server-controlling CPU 81 recognizes the winning chips betted on the winning number at each station 4 and calculates the sum of the payout value of credits to be paid out for each station 4, using the payout value ratios for the respective BET areas 72 (i.e., the numbers of credits to be paid out for a single chip [1 bet]) stored in the payout value credit storage area 82A in the ROM 82.

Next, in step S114, the server-controlling CPU 81 conducts processing for transmitting the result of credit payout in games based on the payout value calculation processing in step S113 and the result of JP payout based on the JP-bonus-game determination processing in step S109. More specifically, the server-controlling CPU 81 issues credit data corresponding to the amount of payout values resulted from games to the station-controlling CPU 91 in the station 4 which won the games. Further, when a JP is generated, the server-controlling CPU 81 further issues credit data corresponding to the JP value accumulated until the present time.

Next, in step S115, the server-controlling CPU 81 transmits a control signal to the roulette device 3 to drive the ball collecting device 108 provided under the roulette wheel 22 for collecting the ball 27 thrown onto the roulette wheel 22. The collected ball 27 will be thrown into the roulette wheel 22 in the roulette device 3 again in subsequent games.

Next, in step S116, the server-controlling CPU 81 adds 1 to the number of games stored in the number-of-games storage area 83F in the RAM 83 and stores the resultant value therein.

In the present embodiment, the number-of-games addition processing is conducted after the collection of the ball. However, the present invention is not limited thereto. For example, the number-of-games addition processing may be conducted at the timing of the receipt of betting information.

Next, in step S117, the server-controlling CPU 81 determines whether or not the number of games has reached a predetermined number (5, in the present embodiment). If the server-controlling CPU 81 determines that the number of games has not reached the predetermined number, the processing shifts to step S121.

On the other hand, if the server-controlling CPU 81 determines that the number of games has reached the predetermined number, the server-controlling CPU 81 determines a series of control data (step S118). More specifically, the server-controlling CPU 81 instructs the CPU 101 in the roulette device 3 to switch the series of control data. On receiving the instruction, the CPU 101 performs random number sampling, and based on the acquired random number, the CPU 101 selects a series of control data different from the series of control data currently set as a reference target, out of the plurality of series of control data stored in the ROM 102.

Next, in step S119, the server-controlling CPU 81 determines pattern data. More specifically, the server-controlling CPU 81 instructs the CPU 101 in the roulette device 3 to switch the pattern data. On receiving the instruction, the CPU 101 performs random number sampling, and based on the acquired random number, the CPU 101 selects pattern data different from the pattern data currently set as a reference target, out of the plurality of pattern data stored in the ROM 102.

Next, in step S120, the server-controlling CPU 81 clears the number of games. Namely, the server-controlling CPU 81 restores the number of games stored in the number-of-games storage area 83F to an initial value of 0.

Next, in step S121, the server-controlling CPU 81 determines whether or not a predetermined time (the 0-th minute at every hour, in the present embodiment) has passed. If the server-controlling CPU 81 determines that the predetermined time has not passed, the present subroutine ends.

On the other hand, if the server-controlling CPU 81 determines that the predetermined time has passed, the server-controlling CPU 81 extracts control data (step S122). More specifically, the server-controlling CPU 81 instructs the CPU 101 in the roulette device 3 to switch the control data. On receiving the instruction, the CPU 101 extracts single control data, out of the plurality of control data constituting the series of control data currently set as the reference target, based on the pattern data currently set as the reference target.

After the processing in step S122, the present subroutine ends.

As described above, the roulette gaming machine 1 according to the present embodiment includes the roulette wheel 22 including the plurality of number pockets 23 which have been associated with respective numbers in advance. Further, the roulette gaming machine 1 includes the ROM 102 (memory) which stores the plurality of series of control data, each of which constituted by the plurality of control data for controlling the roulette gaming machine 1 so as to provide different weights on the probabilities that the ball 27 is housed in any of the above-mentioned number pockets 23. Further, the ROM 102 stores the plurality of pattern data, each of which indicating a pattern to determine control data to be a reference target, out of the plurality of control data constituting a single series of control data selected out of the above-mentioned plurality of series of control data. Further, the roulette gaming machine 1 includes the server-controlling portion 80 (controller) which controls rotation of the roulette wheel 22 and launching of the ball 27, by referring to a single control data extracted, based on a single pattern data determined as a reference target out of the above-mentioned plurality of pattern data, from the above-mentioned plurality of control data, each of which constituting a series of control data. Further, the server-controlling portion 80 extracts, based on the above-mentioned single pattern data, control data which is to be a reference target, out of the above-mentioned plurality of control data, each of which constituting the above-mentioned single series of control data, when a predetermined time has come. Further, the server-controlling portion 80 determines pattern data different from the above-mentioned, single pattern data, out of the above-mentioned plurality of pattern data, as a reference target, when the above-mentioned single series of control data is changed to another single series of control data different from the above-mentioned single series of control data.

In the present embodiment, there has been described a case where the control data is switched, on condition that a predetermined time has come. Namely, there has been described a case where a first predetermined condition according to the present invention is that a predetermined time has come. However, the first predetermined condition according to the present invention is not limited thereto. For example, the first predetermined condition may be that the number of games has reached a predetermined number, that the ball has been continuously housed in the same pocket for a predetermined number of times, that the ball has been continuously housed in any of the pockets in the same group (area) for a predetermined number of times, that a predetermined bonus (for example, a mystery bonus or a jackpot) has occurred, that the currency value betted on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that the currency value which has been paid out as a result of betting on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that a winning relating to a predetermined bet (for example, Straight Bet) has occurred, that a JP cumulative value has reached a predetermined value, that the payment balance between the betted currency value and the paid-out currency value has reached a predetermined value, or that a player has inputted a command for switching the pattern data.

Further, there has been described a case where the pattern data is switched on condition that the series of control data has been changed. Namely, there has been described a case where a second predetermined condition according to the present invention is that the series of control data has been changed. However, the second predetermined condition according to the present invention is not limited thereto. For example, the second predetermined condition may be that the number of games has reached a predetermined number, that the ball has been continuously housed in the same pocket for a predetermined number of times, that the ball has been continuously housed in any of the pockets in the same group (area) for a predetermined number of times, that a predetermined bonus (for example, a mystery bonus or a jackpot) has occurred, that the currency value betted on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that the currency value which has been paid out as a result of betting on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that a winning relating to a predetermined bet (for example, Straight Bet) has occurred, that a JP cumulative value has reached a predetermined value, that the payment balance between the betted currency value and the paid-out currency value has reached a predetermined value, or that a player has inputted a command for switching the pattern data.

In the present embodiment, the series of control data is switched when the number of games has reached a predetermined number. However, in the present invention, the condition which should be satisfied for switching the series of control data is not limited thereto. For example, the condition may be that a predetermined time has come, that the ball has been continuously housed in the same pocket for a predetermined number of times, that the ball has been continuously housed in any of the pockets in the same group (area) for a predetermined number of times, that a predetermined bonus (for example, a mystery bonus or a jackpot) has occurred, that the currency value betted on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that the currency value which has been paid out as a result of betting on numbers which belong to a predetermined group (for example, a group having a higher ball-housing probability) has reached a predetermined amount, that a winning relating to a predetermined bet (for example, Straight Bet) has occurred, that a JP cumulative value has reached a predetermined value, that the payment balance between the betted currency value and the paid-out currency value has reached a predetermined value, or that a player has inputted a command for switching the pattern data.
